Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+	tristate "Fibre Channel and FC4 SCSI support"
+	---help---
+	  Fibre Channel is a high speed serial protocol mainly used to
+	  connect large storage devices to the computer; it is compatible with
+	  and intended to replace SCSI.
+
+	  This is an experimental support for storage arrays connected to your
+	  computer using optical fibre cables and the "X3.269-199X Fibre
+	  Channel Protocol for SCSI" specification. If you want to use this,
+	  you need to say Y here and to "SCSI support" as well as to the
+	  drivers for the storage array itself and for the interface adapter
+	  such as SOC or SOC+. This subsystem could even serve for IP
+	  networking, with some code extensions.
+
+	  If unsure, say N.

+	  Serial Optical Channel is an interface card with one or two Fibre
+	  Optic ports, each of which can be connected to a disk array. Note
+	  that if you have older firmware in the card, you'll need the
+	  microcode from the Solaris driver to make it work.
+

+	  Serial Optical Channel Plus is an interface card with up to two
+	  Fibre Optic ports. This card supports FC Arbitrated Loop (usually
+	  A5000 or internal FC disks in E[3-6]000 machines through the
+	  Interface Board). You'll probably need the microcode from the

+ * just presents a standard SCSI interface to the operating system
+ * (that's e.g. the case with Qlogic FC cards), or leaves most of the FC
+ * bookkeeping to the OS (e.g. soc, socal). Drivers for the former adapters
+ * will look like normal SCSI drivers (with the exception of max_id will be
+ * usually 127), the latter on the other side allows SCSI, IP over FC and other
+ * protocols. This driver tree is for the latter adapters.
+ *
+ * This file should support both Point-to-Point and Arbitrated Loop topologies.
